Some people play for the socialization, some people play for the challenge, and some people play to win (ie, display their “dominance”). It’s just different personalities and values.

The latter group will often cheat if necessary as winning is the need and the priority. The talented ones usually end up in profitable pursuits like business and poker rooms. The losers (pun intended) will gravitate toward friendly competitions where people have their guard down and cheating is easy. At least that’s what I’ve seen.

The best strategy is to detect these people and ban them because appealing to values won’t work.
